It was the first time Nadal had ever been down 2-0 in a 5-set match despite playing 95 of them and sporting a 94-1 record. Obviously it is also the first time that he has lost a 5-set match on clay in straight sets. Now his record is 94-2. He is 70-2 lifetime at Roland Garros, with his only other loss coming in the fourth round of the 2009 French Open to Robin Soderling.
Djokovic is now two matches away from completing the career Grand Slam, which would also be his 9th major title. In the biggest tournaments on the tour, Djokovic has won every single one he has played in 2015 (4 Masters Series 1000 tournaments and the 2015 Australian Open).
